My invention relates to new and useful improvements in a solid wall construction and has for one of its objects to improve the construction of walls by the use of a relatively stiff panel or panels, such as plaster board, through similar items and still or stiffened paper, fabrics and the like.

Another object of the invention is to provide a substantially solid base for plaster in the construction of solid walls and said base is preferably of the same or similar material as the plaster itself and therefore is less likel to deteriorate than where metal lath is use p A further object of the invention is to use a non-metallic base to which plaster is ap plied in the construction of solid walls.

A still further object of my invention is to reduce the cost of constructing solid walls or sub-division partitions between rooms, by the elimination of one application of plaster or what is known as the scratch coat. This is true because the base, or what will be generally referred to throughout this description as plaster board, takes the place of metal lath and the scratch coat of plaster and on one side of said base is applied a backing-up coat to fill out the space between said base and the faces of the supports opposite those on which the base 1s secured, after which a straightening coat is applied to the opposite face of the base and to the backing-up coat, and said straightenlng coats then covered with finishing coats.

' With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, ll will describe its construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which Fig. 1, is a perspective, view of the working face or front of a wall prepared for the reception of the plaster in the production of a solid wall according to my invention.

Fig. 2, is a horizontal sectional view of the intersection of two walls, thereby providing a corner or division of space, illustrating the manner in which my invention will lock the base material'of the walls when it is necessary to start building from another wall of the same material and plainly showing the use of a base and five coats of plaster instead of a base and six coats as is usual.

In carrying out my invention as herein embodied, the line of the wall is designated, and this line then spaced off at intervals, after which the supports 3, such as studding or furring bars are erected. A paneLor sheet of plaster board 4 or other suitable stiff material is then set in place with one end abutting the starting point or vertical wall and said sheets or panels are preferably so arranged that the vertical jolnts of contiguous panels are out of alignment orin staggered relation and located between the studs or furring bars, as lainly shown in Fig. 1. These anels or s eets are then secured to the studding or furring bars in any suitable manner and for convenience of illustration,

I have shown clips 5 projecting completely across the faces of the sheets or panels and with their ends passing around the edges of the sheets and engaging the studding or furring bars.

As suggested, the clips are shown only for convenience of illustration and any other fastening means may be substituted therefor, as will be obvious to those skilled in this art. The vertical meeting edges of the sheets or panels may also be fastened together by means of clips or ties 6. By utilizing this particular method of erection, the lower edges of succeeding higher sheets or panels rest upon the preceding lower ones and by causing the ends of one set of sheets or panels to overlap the ends of the other, all the vertical joints are broken, as it is called in the trade.

After the desired number of sheets or panels are-erected to form the base for the wall being constructed, a backing-up coat 7 of plaster is applied to one side only of the base formed by the sheets or panels of stiff material 4, preferably plaster board, and as plainly shown in Fig. 2, this backing-up coat is placed only on the side of the base which lies against the studding or furring bars in order to fill up the space between said studding or furring bars and for convenience of description, I will term this the back or rear face of the base.

Next, a straightening coat 8 of plaster is applied to the backing-up coat of laster and a similar straightening coat 9 oi plaster is applied to the front or outer surface of the base. After these last mentioned coats of plaster are in place, the finishing coats 10 of plaster are applied to the straightening coats, so as to cover the latter and give a finished appearance to the wall.

Ordinarily, in the construction of a'wall of this character, lathing-is first fastened to the supports and a scratch coat of plaster applied thereto, particularly where metal lathing is used. After the scratch coat has dried, the backing-up coat is applied to fill out the space between the lath and the faces of the supports opposite those on which the lath is secured, after which two applications of straightening coats are made and each of these covered with the finishing coat, so that six coats of plaster are actually applied, and

the first coat in particular must be allowed to dry for approximately twenty-four hours before the other coats can be put on.

With the use of my invention, there is a considerable saving in time, labor and material because the plaster board takes the place of both lathing and scratch coat of plaster and being already properly cured,

the coats of plaster can be applied imme diately and as the scratch coat is eliminated there are only five coats of plaster applied. The elimination of this one coat of plaster saves considerable material and labor as well as the time which is required to permit the same to dry.

Of course I do not wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claim without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new and useful is A solid wall construction including supports, a base consisting of a plurality of panels of stiff material, means to secure said panels to the supports, a backing-up coat of plaster on'the back of the base, a straightening coat of plaster on both the backing-up coat and the front of the base, and a finishing coat on each straightening coat.

In testimony whereof, I have hereunto affixed my signature.

JOHN S. RAYNOR.
